He might be too young to have a
Facebook account, at least according to Mark Zuckerberg'srules, but Jani (full name not revealed) has just been handed $10,000 by the social media giant for uncovering a flaw in Instagram. The 10-year-old Finn became the youngest ever recipient of a Facebook bug bounty after uncovering a vulnerability that allowed him to delete any comment on the photo sharing application.

The Helsinki-based wunderkind, according to Finnish publication Iltalehti, discovered he could alter code on Instagram servers to force delete users' words. "I would have been able to eliminate anyone, even Justin Bieber," he told the paper (translated).

Facebook told FORBES that Jani verified his report by deleting a comment the company posted on a test account. A spokesperson confirmed the bug was patched in late February and the $10,000 reward handed to Jani in March. The problem lay in a private application programming interface (the slice of code allowing certain outside access) that wasn't properly checking the person deleting the comment was the same one who posted it, the spokesperson added.

Some serious bugs have been found in Instagram in recent memory. Not all have gone rewarded, as in the case of researcher Wes Wineberg, who uncovered "shocking" bugs in December 2015 that allowed him access to a vast amount of internal Instagram data. Facebook believed he'd gone too far in proving his point, denying Wineberg a bounty.

Given Jani's auspicious start, he could become a top whitehat hacker. He told Finnish media he started picking up hacking skills from YouTube videos and now wants to join the industry. "It would be my dream job. Security is really important."

Like any sensible kid, Jani plans to spend his earnings on football and a new bicycle.
